It has been stated that the interior of the right ventricle is as unique to each individual as one's fingerprint. This statement is backed by numerous publications which demonstrates considerable variation in the number, shape and configuration of papillary muscles inside the normal right ventricle. It has also been shown that these variants may be the cause of cardiac rhythm disorders. In this case report another potential complication of such right ventricular papillary muscle variants is proposed—these muscles may be the source of pulmonary emboli. The pathogenesis may be that of local stasis around these aberrant muscular structures and/or emboli may form inside the right ventricle as a result of cardiac rhythm disorders, induced by these muscles. It is proposed that in future the role of the right ventricle as the source of pulmonary emboli will become more apparent and an important part of the diagnostic work up in cases of idiopathic pulmonary embolism.

ObjectivesTo investigate how many general practitioner (GP)-referred venous thromboembolic events (VTEs) are diagnosed during 1 year in one geographical region and to investigate the (urgent) referral pathway of VTE diagnoses, including the role of laboratory D-dimer testing.DesignHistorical cohort study.SettingGP patients of 47 general practices in a demarcated geographical region of 161 503 inhabitants in the Netherlands.ParticipantsWe analysed all 895 primary care patients in whom either the GP determined a D-dimer value or who had a diagnostic work-up for suspected VTE in a non-academic hospital during 2015.Primary and secondary outcome measuresThe primary outcomes of this study were the total number of VTEs per year and the diagnostic pathways—including the role of GP determined D-dimer testing—of patients urgently referred to secondary care for suspected VTE. Additionally, we explored the use of an age-adjusted D-dimer cut-off.ResultsThe annual VTE incidence was 0.9 per 1000 inhabitants. GPs annually ordered 5.1 D-dimer tests per 1000 inhabitants. Of 470 urgently GP-referred patients, 31.3% had a VTE. Of those urgently referred based on clinical assessment only (without D-dimer testing), 73.8% (96/130) had a VTE; based on clinical assessment and laboratory D-dimer testing yielded 15.0% (51/340) VTE. Applying age-adjusted D-dimer cut-offs to all patients aged 50 years or older resulted in a reduction of positive D-dimer results from 97.9% to 79.4%, without missing any VTE.ConclusionsAlthough D-dimer testing contributes to the diagnostic work-up of VTE, GPs have a high detection rate for VTE in patients who they urgently refer to secondary care based on clinical assessment only.

The work-up and management of patients with acute liver failure in paediatric critical care are often challenging. This chapter takes the readers through definitions, grading of severity, and diagnostic work-up of acute liver failure in children. General principles underlying the management of acute liver failure, including immediate resuscitation and retrieval; organ support, including renal replacement therapy; and the management of complications, including bleeding, are discussed. In particular, this chapter focuses on neuromonitoring and neuroprotection strategies in children with hepatic encephalopathy as a complication. The role of liver transplantation in fulminant liver failure and a brief overview of complications are also discussed.
